Sorry but that schematic is wrong.Is it safe to use a voltage doubler on one secondary of a power transformer if the other secondary is a high voltage full wave referenced to ground?
Transformer tap #6 will be shorted to ground on negative semicycles.
And tap #8 is shorted to ground all the time through the bottom 470uF capacitor.

Wait just a second.
The answer to that question is yes. But that's not what you have. You don't have "one secondary" and the "other secondary". You have one secondary with multiple taps. That's a different kettle of fish. You need to make sure it's properly designed and wired. As said, you have a short in there.
Make sure it's all correct and run a sim if in doubt. Otherwise things can go boom ouch.

yes, and he can learn it the hard way....i did once and never going there again..
The "full wave" doubler shown can't share a common with anything else on the transformer.
Thanks, that's what I suspected, I just wanted confirmation.
With the current (external) power supply, I am using two OD3 off of the B+ and that works fine. I am building a new power supply for the amp with greater current capability and the second set of taps off the secondary was tempting me to use them.
The half wave doubler appears to be a practical approach.

Here you go. Blue trace is a bit hard to see, around 340V
yes, this is how to do it...
